Me - 74kg old weak legs so need a big board to get up from kneeling. Back a bit, I demoed the 125l Naish DW board and didn't feel any benefit compared to my Fanatic Bee other than lighter. Both got me foiling in light wind about the same.
A week ago, I had the opportunity to demo the 105l, which is 2.5 in narrower and only 5.7kg. What a difference, not only could I get up from kneeling ok it accelerates amazingly and does most things better.
So, I bought one.
